TUBE QONTRACTOR FOR RIVETING-MACHINES.

Patented Sept. 3, 1918.

Application filed January 4,1917. Serial No. 140,625.

of Minnesota, have invented certain new.

and useful Improvementsin Tube-Contractors for Riveting-Machines; and I do hereby. declare the followin to be afull, clear, and exact description of the invention, such as will enable others skilled in fthe art to Which I it appertains to make and use thesame.

My invention relates to punch and rivetlng machines, and especially-to those used for punching and riveting corrugated sheet metal culverts, and,provides,- as an attachnow'invery generaluse, are made with overlapped longitudinal seams connected by rivets and the sections are ,comiected together 1 by telescopin'gthe corrugated ends. -This telescoping of the'ends' of the culvert sece tionsnecessitates leaving out at least some of the rivetsimmediately adjacent, to the ends to be telescoped. Practice has shown that where the tubes are .thus telescoped and then punched and riveted, it is necessary to hold the same contracted by some:

suitable" contracting device while at least the first punch is being made andthe first connecting rivet applied. My invention is directed primarily to an improved tube con- 1 tracting device forthe above purposeq In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several 5,

views. a

Referring to the drawings:

were. This feature, however, constitutes no, part of thepresent invention.

. The; press head 7 carries the usual punch 15.,a11d hammer 16 which cooperate, respec 'tively,with a punch die 17 and anvil block I u p 18 on theprojected end of the hornf6. ment thereto, a simple and efficient device I for contracting the endsof the telescoped I culvert sections while at least the first connecting rivet is being applied thereto.

Thesecorrugatedsheet metal culverts, as

Loosely mounted on the projecting front erally projecting flange of" the Windlass drum,19 is a disk-like clutch shoe carrier 21 towhich clutch shoes 22 are pivoted. These shoes 22 are connected by oblique or toggleactinglinks 23 to a shipper hub 24 that is rotatable with but slidable on the said shaft 9.

' The numeral 25 indicates a bearing frame that is rigidly secured to the end of the main frame 5 adjacent to the vertically movable I press head Wand is provided with depend [ing portions in'which is mounted a horizontalslide 26 having at one 'end a stripper arm 27 adapted to bemoved toand from engagement with the culvert section or tube, and when 1n operat ve positlon, servlng to hold down the tube and strip the samefrom the upwardly moving punch.

The numeral 28 indicates a shlpper lever pivoted at one end to alug on the bearing frame j 25 and having pins 29 that engage an annular groove in the shipper hub 24.

The numeral 30 indicates a Windlass latch leverpivoted to a projection of the bearing frame 25 and having a lock or retaining dog 31 that is normally engageable with the latch flange 20 'of the Windlass drum 19.

The clutch mechanism and Windlass drum 32 indicates anoverhead track supported weightedtruck or traveler mounted to run on the lower flanges of the rail A bar guide sheaves 46, 47 and 34 is intermediately supported from the frame of the truck 33, as shown, by a short chain 35, and to one end of this bar is pivotally connected the upper end of a long upright floating column 36., This so-called floating column ispreferably 'made'up of a pair of laterally spaced bars, between the lower ends of which is rigidly but ad ustably secured a laterally projecting anchor 37. The adjustment between the anchor 37 and the lower ends of the barsof the column 36 is'shown as made by pins 38 and cooperating perforations 39.

The free end of thebar 34 is adjustably connected to the intermediate portion of the column 36 by means of a truss bar 40, the lower end of which, as shown, is perforated and arranged to be adjustably connected by a pin 41 to a metal strip or bracket 42 on the said column. By adjustments of the truss bar 40, the lower end of the floating column, and hence the anchor 37, may be adjusted. A contracting cable '43 is detachably connected at one end to the anchor 37, by means of a hook 44, or the like, and the other end of this'cable is attached to the Windlass drum 19, by means of a staple 45, or the like.

36 and bar 34. The corrugated sheet metal culvert sections are indicated by the character a and their longitudinal seams are indicated by the character a. Of the culvert sections shown in Fig. 1, that at the left is the pivotally riveted section and may be connected to others farther at the left, but the culvert section at the right isin the process of completion and may be assumed to have its joint a connected only by one rivet located about two corrugations from its right hand end.

At its left hand end, the said right hand culvert section has its joint a loose, but is telescoped over the righthand end of the left hand culvert section and is ready for connection thereto by the application of a rivet applied at the overlapped end portions of the two culvert sections. Before this is done,

however, the said left handend of the right hand culvert section should be contracted tightly against the right hand endv of the left hand culvert section and this is accomplished as follows:

The lower end of the contracting cable 43 is passed around the left hand end of the said right hand culvert section, say at the third corrugation thereof, and is attached to the anchor 37. Then by manipulation of the lever 28, the friction clutch is set and the Windlass drum 19 will be rotated, until the proper contraction of the tube or culvert section is accomplished, and then the clutch I is, of course, released. The retaining dog 31 will automatically lock the cable under this set tension. Then the hole is first punched This cable 43 is passed over 48 on the column through the overlapped ends of the two culvert sections at the joint of the outer thereof; next, a rivet is applied through this punched hole; and then the rivet is upset between the hammer 16 and anvil block 18. After this has been done, the tension on the contracting cable is released by raising the lever 30, and the lower end of the cable may be detached from the anchor 37 and the derrick moved toward the right, or otherwise, to a position out of the way, while the punch and riveter is used to complete the riveting adapt itself to culvert sections or tubes of very greatly dilferent diameters. However,-

from the broader point of view, this socalled Windlass drum is an oscillating clutch actuating cable take-up device or tightener.

What I claim is:

1. A machine for contracting culvert sec-' tions, and the like, comprising a cable, an anchor for holding one end of said cable while it is wrapped around the culvert section, and a driven clutch actuated cable takeup device applied to the other end of said cable.

21A machine for contracting culvert sections, and the like, comprising a cable, an

thereof, and a clutch actuated power-driven cable take-up device applied to the other end of said cable.

4. A machine for contracting culvert sections, and the like, comprising a cable, a floating derrick frame having guides for said cable and an anchor for the lower end thereof, a clutch actuated power driven cable take-up device applied to the other end of said cable, and a pawl and ratchetdevice releasable at will but operative automatically to lock said cable under its set tension.

- 5. The combination with a riveting machine having an anvil, of a tube contracting device operated from one of the running parts of saidriveting machine and arranged to contract a tube positioned on said anvil.

6. The combination with a power-driven from one of the running parts of said rivetsaid anvil and to be put under tension 10 ing machine and arranged to contract a tube through the controller of said clutch.
